Which of the following statements about osmosis is correct?

Biology
1 answer:
Pavlova-9 [17]3 years ago
5 0

Answer:

D. The presence of aquaporins (proteins that form water channels in the membrane) should speed up the process of osmosis.

Explanation:

Water moves in the cells through osmosis which means water moves from its higher concentration to lower concentration. In many animals and plants, water channels are also present which is called aquaporins which allow the water to move through it in and out of cell more quickly.

The rate of diffusion by channel proteins is higher than simple diffusion therefore the aquaporins speed up the process of osmosis. No ATP is required to transport the water through aquaporin channel proteins.

Which of these processes does not require the cell to use energy A cell division b protein synthesis c DNA replication D diffusi
weeeeeb [17]

Answer:

D diffusion across a membrane

Explanation:

Based on whether or not energy input is required, there are two types of processes viz: passive and active. Passive processes are those that do not require energy input in form of ATP while active processes require energy input to occur.

An example of passive process is DIFFUSION, which is the movement of molecules from a region of high concentration to a region of low concentration across a membrane. Diffusion is passive i.e does not require energy, because movement occurs down a concentration gradient.

Other processes in the options like cell division, DNA replication and protein synthesis all require energy input to occur.

Question 4....??? What effect can bottleneck events have on population that have nearly become extinct????
ArbitrLikvidat [17]

The answer is; D

It reduces the diversity of the population because some variations in the population can be completely eliminated by the bottleneck effect. Even if the population recovers in population size, the genetic variation will have reduced as compared to the initial population before the bottleneck. For a mall population, this effect can be grave because the reduced genetic variation may mean that the population may be unable to adapt to new selection pressures hence may go extinct.

A science club has 16 members. How many ways can a president, a vice president, and a treasurer be selected from the members?
boyakko [2]

Answer:

The answer would be D. 3,360

Explanation:

The solution is found by multiplying 16 times 15 times 14. The club has 16 members and after one role (president) is filled, there are 15 left to fill the next (vice). The same goes for the next role (treasurer). So 16 is multiplied with 15, then 14. This is more of a math question that biology btw.
